Perf shows a relatively high rate (about 8%) race in
spin_lock_irqsave() when doing netperf between external host and
guest. It's mainly becuase the lock contention between the
tun_do_read() and tun_xmit_skb(), so this patch do not put self into
waitqueue to reduce this kind of race. After this pat

Page flip every time we copy the buffer over instead of invalidating
rects.
This should improve performance by letting hardware do the page
flipping.

This should be a single '=' -- '==' is a bashism. The 'checkbashisms'

This helps reducing our build-time checks for feature support in the
available Linux kernel headers. And it helps users that do not have
sufficiently recent headers installed on their build machine.
Consequently, the patch removes and build-time checks for kvm and vhost
in configure, the --kerneld
kvm_arch_get_supported_cpuid checks for global cpuid restrictions, it
does not require any CPUState reference. Changing its interface allows
to call it before any VCPU is initialized.
